What is pollination? how are insect pollinated and wind pollinated flower is different from each other

Answers 2

Answer:

Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.

In wind-pollinated flowers, the produced pollen grains are smaller and lighter in weight, which can be carried by the wind easily. In insect-pollinated flowers, the produced pollen grains are larger in size, sticky and spiny which helps the insect to carry the pollen grains.

Explanation:

What is pollination?

Pollination can be defined as the natural process of transferring pollen grains from the anther (male reproductive part) to the stigma (female reproductive part) of a flower. This process can be carried out either within a flower or between flowers of the same plant or flowers of different plants.

Pollination

Based on the transfer of pollen grains, pollination has been classified into two different types:

Self Pollination –— Self-pollination is the initial type of pollination, which occurs by transferring the pollen grains directly from anther into the stigma of the same flower. Sunflowers and orchids are the best examples of self-pollinated flowers.

Cross-Pollination — Cross-Pollination is the complex type of pollination, during which the pollen grains are transferred from the anther of the flower into the stigma of a different flower. Tulips, dandelions and daffodils are the best examples of a cross-pollinated flower.

Insect Pollinated and Wind pollinated flowers: Differences

Wind pollinated flowers Insect pollinated flowers

Pollinating Agent

The pollinating agent is wind. The pollinating agents are an insect.

Morphological features of a Flower

The wind-pollinated flowers comprise light coloured petals, without a pleasant strong smell. The insect-pollinated flowers comprise brightly coloured petals with a pleasant strong smell.

Pollen Grains

In wind-pollinated flowers, the produced pollen grains are smaller and lighter in weight, which can be carried by the wind easily. In insect-pollinated flowers, the produced pollen grains are larger in size, sticky and spiny which helps the insect to carry the pollen grains.

Stigma

Stigma is feathery or sticky and found hanging out of petals. Stigma is small and is situated deep inside the petals.

Stamens

The stamens are long and visible out of petals. Stamens may be small and hidden inside petals.

Anther

The anthers are often seen being supported outside the flower The anthers are found deep inside the flower.

Filaments

The filaments found in these flowers are slender and long. The filaments found in these flowers are strong and short.
